摘　　要：尿道狭窄疾病是男性泌尿系统的常见疾病之一。准确的尿道狭窄影像学诊断是选择手术方式的关键。目前,X射线尿道造影只能提供尿道腔的形态,但不能显示尿道周围的结构;尿道超声检查具有明确尿道腔及其周围组织的能力,并且在无辐射照射的情况下能动态观察尿道周围组织纤维化的程度;多层螺旋CT尿道成像的优点是无需调整体位,快速扫描并三维图像重建,可以精准呈现尿道狭窄段的位置、长度和程度及其与周边组织的空间关系;尿道磁共振成像能提供更多尿道狭窄和尿道周围软组织的有价值的信息,特别在骨盆骨折致后尿道狭窄和复杂性尿道狭窄等情况下。影像学检查方法的选择应充分根据病因、解剖、尿道狭窄的类型和患者的一般情况而定,选择合适的影像学方法可提高尿道狭窄的诊断准确率。Urethra stricture is one of the most common diseases of the urinary system.Accurate imaging diagnosis is key to the selection of surgical approach.At present,X-ray urethral imaging can show the form of urethra cavity,but not the tissues around the urethra.Sonourethrography(SUG)can dynamically identify the urethral cavity and the surrounding tissues without radiation exposure.Multi-layer spiral CT urethrography(CTU)has advantages of no need to adjust the position,quick scanning and reconstruction of the three-dimensional image,which can accurately show the location,length and degree of urethral stricture,and the spatial relationship with the surrounding tissues.Magnetic resonance urethrography(MRU)can provide useful information of the urethral stricture and soft tissues around the urethra,especially in urethral strictures caused by pelvic fractures and complex urethral stenosis.The choice of imaging method should be based on the etiology,anatomy,types of urethral injury and the general situation of patients.Appropriate imaging method can improve the diagnostic accuracy.
